Made of CPVC, these flanges can handle high temperatures up to 200° F. They meet NSF/ANSI Standard 61 for drinking water. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Also known as Class 150 flanges, they have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing and waste water treatment. Flanges have good corrosion resistance. They meet ASTM D1784 specifications and testing requirements for material quality. They are comparable to Corzan.

Warning: Never use plastic pipe flanges and pipe with compressed air or gas.

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local regulatory limits on VOCs (Volatile Organic Compounds).

Made of polypropylene, these fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light and are suitable to use outdoors. They have the chemical resistance to withstand a wide variety of acids, solvents, and other harsh substances. Apply a non-hardening, plastic-compatible sealant to the male threads to prevent leaks. Tape or sealants with PTFE are not recommended for plastic-to-plastic threaded connections. When making a threaded connection be careful not to overtighten the threads. To prevent cracks and leaks, finger tighten the fitting, then wrench-tighten one to two turns.

Schedule 80 fittings have thicker, stronger walls than Schedule 40 fittings for heavy duty, industrial chemical processing applications.

Warning: Never use plastic pipe fittings and pipe with compressed air or gas.

Sealants cannot be sold to Colorado, Connecticut, District of Columbia, Delaware, Illinois, Indiana, Massachusetts, Maryland, Maine, Michigan, New Hampshire, New Jersey, Northern Virginia, New York, Ohio, Pennsylvania, Rhode Island, or Utah due to local VOC (Volatile Organic Compounds) regulations.

Also known as manifold flange fittings, these have a clamp-together design that lets you access your line for routine maintenance. Connect the flanged end to another quick-clamp fitting with a clamp and a gasket (all sold separately). Fittings are polypropylene, which resists a wide variety of acids, solvents, and other harsh chemicals. The fittings won’t deteriorate when exposed to the damaging effects of ultraviolet light, so they’re suitable for outdoor use.

Flanges have excellent corrosion resistance to handle a wide range of acids and other highly-corrosive chemicals. Use in metal surface treating applications, plating solution lines, and other chemical process applications. They are reinforced with fiberglass layers for better strength and durability than any of our other pipe flanges for chemicals. Bolt two same-size flanges together with a gasket (sold separately) to create an access point within a line. Flanges meet ASTM D4024 specifications and testing requirements for product dimensions, performance, and material quality.

To connect flanges to pipe, first sand the inside of the flange and the end of the pipe to remove the surface finish. Next, mix the adhesive (sold separately) until the color is uniform with no streaks. Apply a thin layer of mixed adhesive to the sanded area of the pipe, approximately 1/8” thick. Repeat this process with the inside of the flange, applying a layer approximately 1/16” thick. After sealant has been applied, push the flange onto the pipe until it is fully engaged. Make sure you align the bolt holes prior to installing to minimize rotation after the flange is installed. Finally, use the adhesive-curing heat cable (sold separately) to cure the adhesive. Wrap the tape around the pipe and flange at the joint, taking care to not overlap the tape. Once you have waited the full cure time, the pipe and flange will be ready to use.

Warning: Never use plastic pipe flanges and pipe with compressed air or gas.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push, and an internal gripping ring and fluoroelastomer O-ring hold the tubing tight. To disconnect, push on the release ring and pull the tubing out of the fitting.

PVDF fittings offer excellent chemical resistance, and can be used with hydrochloric acid and nitric acid. They withstand temperatures up to 270° F, higher than other push-to-connect fittings for chemicals. They are produced in a clean room and are bagged individually to prevent dirt and moisture from contaminating the inside. PVDF is also known as Kynar.
